Hi!

  I have a problem.

   I'm trying to install the newest version of Draftsight.(x64) V1R5.0 on my pc where I have the default user directory on a NAS disk with label W:\\
When I launch the installation program it said me Invalid Unit W:\\  How can I siolve this problem?
 

The  version 1R3,1 didn't give me any error with the W:\\ unit.
